The Grizzlies' active summer continues. A source close to proceedings indicates the team is getting close to a deal with point guard Shelvin Mack, an NBA veteran most recently with the Orlando Magic.

Mack's signing would bring the Grizzlies to 16 players on their roster, one more than would be allowed in the regular season. He would join a suddenly crowded backcourt including Mike Conley, new draftee Jevon Carter, Andrew Harrison, and two-way player Kobi Simmons (though Simmons doesn't could against the Grizzlies roster number as a two-way player). Harrison's contract, for roster purposes, is only partially guaranteed until January 10th.

The potential move was first reported by ESPN's Adrian Wojnarowski.

Free agent guard Shelvin Mack and the Memphis Grizzlies are progressing in talks on a one-year deal, league sources tell ESPN.

Mack is considered another solid locker room presence, a common theme among Grizzlies acquisitions this offseason. He was part of the Orlando Magic team last year that coincidentally featured now-Grizzlies assistant Chad Forcier as part of their coaching staff. Mack was lauded for his willingness to mentor young players like Jonathan Isaac, and he would be asked to do the same with Grizzlies blue-chip prospect Jaren Jackson Jr.

The deal is not finalized yet. Once it is, it's expected to be a one-year deal at the league minimum.
